Trestle bracing.

Interesting article. I just wonder if the current G6122-1959 Country Gentleman have the trestle bracing or not? They list the G6122-1958 Country Gentleman, but not the 59. My G6122-1959HOF Country Gentleman has the trestle bracing, I thought that I had read that all of the G6122-1959's have this type of bracing instead of the "waffle bracing" that they had at first.
